All things considered, it was a reasonable time limit in Nathan's opinion, as he himself wouldn't have been so generous. Taking the implied threat with good grace, he took the pen from her and drew a small line just before the hour mark, tapped it, then pointed to one wall – the one that connected Rachel and Annie's room with Mantis'. If Peter wasn't back with Annie within the hour, they would go get the only other man who could find both, as well as deal with any problems Peter might be having with Annie. But Nathan didn't believe it would come to that.
He tapped the image again, this time over the figure of Annie, then held up his hand, fingers and thumb formed into the nearly universal symbol for 'okay' before smiling encouragingly. Though he understood her anger and fear, and would have felt it himself if anyone had disappeared with Peter, he did know Annie would be just fine and would be back as soon as she was calm.
